Share New Research 
I have read this, this, this, and other posts. It's not clear yet how I can create a candlestick chart based on the daily OHLC values and colour each candle according to some rules. (I don't want to run on a minute/hour resolution in order to build the chart.). My goal is create a chart that looks like this: https://www.tradingview.com/x/xgeqDHzM.
Secondary problem: Whenever I tried using a smaller resolution, I'd get a weird error: ‘NoneType’ object has no attribute Close.
Should I be approaching this differently? Maybe I shouldn't be trying to use QuantConnect's charting functionality and should, instead, be using matplotlib? If so, maybe I should be moving my work over to a Notebook instead?

Hey Jason,
what exactly do you want to use the plotting for? Because the answer to your question will differ based on that.
Thanks!

Ya, good question. The rules that dictate what colour the candles are is a component of a strategy. I don't need to plot in order to execute the strategy, obviously. However, it's handy to see the buy/sell signals on the chart alongside the coloured candles so that I can easily inspect what it did and why.

Hm I see, there are currently many issues with plotting candlestick charts in QC, especially in lower resolution and I am not aware that you can customize it easily either. If all you need the plotting for is visualizing to inspect it, then I would suggest plotting it in the research environment and using something like mplfinance or matplotlib, which will also give you much more control over the plotting,
thanks!

Plotly is also an additional option, https://plotly.com/python/candlestick-charts/.
